It’s past the time for Canada to start cutting as many ties with the US as humanly possible. No more F-35s. Ditch the autopact and make one with Asia, Africa and Europe. Make individual trade deals with some states perhaps and treat those more like sovereign countries. Treat the US like the fascist country it has become.
There’s no doubt that not having the US in NATO weakens it, but if they’re going to act like the enemy maybe NATO would be better off.
